目的:评估种植修复前附着龈增宽的临床意义。方法:选择临床上附着龈不足的种植病例56例70个区域,种植Ⅰ期手术时全部采用埋入式愈合,种植Ⅱ期手术前通过软组织增量技术,即附着龈增宽术使附着龈不足的区域增加附着龈。附着龈增宽术主要采用带蒂瓣、游离龈移植和人工移植物三种方法。在Ⅱ期手术前、后分别检查附着龈增加的宽度。结果:56例70个区域附着龈宽度均明显增宽,增宽的幅度在3mm-5mm之间,增宽的附着龈颜色和质地均与正常附着龈组织相似。修复后临床效果良好,种植体周软、硬组织稳定。讨论:种植体与天然牙的结构是不同的,种植体比天然牙更容易遭受细菌和机械性的侵害。临床上,种植体周附着龈不足或缺少附着龈时往往会出现种植体周围粘膜炎和种植体周围炎,造成种植修复病例失败。随着种植修复技术在临床上应用越来越多,对种植体周软组织的关注也越来越高。增宽附着龈有助于预防种植体周围炎,有助于种植修复的长期成功。结论:附着龈增宽后有助于消除炎症,对种植体的长期成功有重要意义。 Objective: To evaluate the clinical significance of gingiva widening before implant repair. Methods: 56 cases with gingival insufficiency in clinical practice were enrolled in this study. All of the 70 cases were treated with embedded healing in stage Ⅰ operation. Soft tissue augmentation technique was used before stage Ⅱ operation. The area of ​​the attached gingiva. Gingival extension of the main use of pedicled flap, free gingival graft and artificial graft three methods. Preoperative and postoperative Ⅱ, respectively, check the increase in the width of the attached gingiva. Results: The gingiva widths of all the 70 cases in 56 cases were obviously widened, with the widening range of 3mm-5mm. The widened gingiva color and texture were similar to the normal gingival tissues. After the repair, the clinical effect is good, the peri-implant soft and hard tissue are stable. Discussion: Implants are different from natural teeth in that implants are more susceptible to bacterial and mechanical damage than natural teeth. Clinically, implant peri-implant gingival insufficiency or lack of attachment of gingiva tend to occur around the implant mucositis and peri-implantitis, resulting in implant failure cases. With the clinical application of implant repair technology more and more attention to the peri-implant soft tissue is also getting higher and higher. Broaden the gingiva to help prevent peri implant inflammation, contribute to the long-term success of implant repair. CONCLUSION: Widened gingiva helps to eliminate inflammation and is of great importance to the long-term success of implants.
